This location in the Northern Temperate Zone experiences distinct seasonal variations in solar energy production.
Seasonal Solar Performance
Summer stands out as the most productive season, with an average daily output of 5.36 kWh per kW of installed solar capacity. Spring follows closely behind, generating 5.17 kWh/day. Autumn sees a significant drop to 3.63 kWh/day, while winter experiences the lowest output at 2.98 kWh/day.
The substantial difference between summer and winter production highlights the impact of seasonal changes on solar energy generation in Eumseong-gun. The longer daylight hours and higher sun angles during summer contribute to peak performance, making it an ideal time for solar energy harvesting.
Optimal Panel Tilt
For fixed panel installations in Eumseong-gun, North Chungcheong, the ideal tilt angle to maximize year-round solar production is 33 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.
Environmental Considerations
While Eumseong-gun generally provides good conditions for solar energy production, there are some environmental factors to consider:
- Seasonal monsoons: South Korea experiences a monsoon season, typically from June to September, which can lead to increased cloud cover and rainfall, potentially reducing solar output.
- Air pollution: Industrial activities and urban pollution can sometimes affect air quality, slightly diminishing solar irradiance reaching the panels.
Preventative Measures
To mitigate these environmental challenges and optimize solar energy production in Eumseong-gun, North Chungcheong, consider the following measures:
- Install high-quality, weather-resistant panels capable of performing well in varying conditions.
- Implement a robust cleaning schedule to remove dust and pollutants, especially during drier periods.
- Consider using microinverters or power optimizers to minimize the impact of partial shading on overall system performance.
- Explore the possibility of tracking systems to maximize energy capture, particularly during the more productive summer and spring months.
By implementing these strategies, solar installations in Eumseong-gun can effectively harness the available solar resources throughout the year, despite seasonal variations and environmental challenges.

Solar output per kW of installed solar PV by season in Eumseong-gun
Seasonal solar PV output for Latitude: 37.1106, Longitude: 127.6342 (Eumseong-gun, South Korea), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 33° South in Eumseong-gun, South Korea
To maximize your solar PV system's energy output in Eumseong-gun, South Korea (Lat/Long 37.1106, 127.6342) throughout the year, you should tilt your panels at an angle of 33° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Eumseong-gun, South Korea
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Eumseong-gun, South Korea. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 21° South in Summer | 42° South in Autumn | 52° South in Winter | 30° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Eumseong-gun, South Korea
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Eumseong-gun, South Korea.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Eumseong-gun, South Korea
Eumseong-gun is a county located in North Chungcheong Province, South Korea. The topography of this area is characterized by a mix of low-lying plains and gently rolling hills, typical of the central region of the Korean Peninsula. The landscape is generally mild, with elevations ranging from about 50 to 300 meters above sea level.
The area around Eumseong-gun features a network of small rivers and streams that flow through the valleys between the hills. These waterways have, over time, carved out shallow valleys and contributed to the formation of fertile alluvial plains. The region also includes some forested areas, particularly on the steeper hillsides and higher elevations.
In terms of suitability for large-scale solar PV (photovoltaic) installations, the most appropriate areas would likely be found in the flatter, open spaces within and around Eumseong-gun. The gently sloping hillsides facing south or southwest could also be potential candidates, as they would receive more direct sunlight throughout the day.
Ideal locations for solar PV projects would be areas with minimal shading from trees or mountains, good access to existing infrastructure (such as roads and power lines), and limited conflict with agricultural or residential land use. The low-lying plains in the region, particularly those not currently used for intensive agriculture, could be well-suited for solar farms.
It's worth noting that while the topography of Eumseong-gun is generally favorable for solar PV installations, other factors such as local climate conditions, land availability, and proximity to power transmission infrastructure would also need to be considered when determining the most suitable locations for large-scale solar projects in the area.
